1 oVerVIeWF300 Megablocks are DIN-rail mounted, device couplers for Foundation™ fieldbus or Profibus PA networks. They allow connection of field devices to the segment trunk cable and provide short-circuit protection to the segment.

Megablocks minimize hand wiring and allow individual devices to be added to and removed from the segment without disrupting network communication.

Megablocks are available in four, eight, and twelve port versions. Multiple Megablocks are easily wired together to allow larger segments to be constructed.

Each F300 Megablock includes an F97 Terminator for installation in the trunk terminals, which is clearly marked with a large ‘T’ for easy identification by field personnel.

Individual surge-protector modules (FS32) can also be fitted to any of the Megablock fieldbus terminals to provide protection against induced surges and transients that can potentially destroy or degrade certain components inside the F300 Megablocks.

2 DescrIPtIoNsimple and reliable interconnection

Each Megablock has dedicated connections for the fieldbus “home run” or trunk cable. Trunk connections are identified by their black connectors. Numbered (grey) connectors are provided for each spur.

Wiring connections to the Megablock are made using pluggable connectors (screw terminal type are standard, but other connection styles are available). These allow wire terminations to be made to the individual connectors, which are then plugged into the Megablock. Devices can be connected and disconnected easily during commissioning. On completion, the connector retaining screws are tightened to secure each connector to the Megablock.

short-circuit protection

To minimize susceptibility to single points of failure, F300 Megablocks are provided with built-in SpurGuard™ short-circuit protectors, which prevent the entire Fieldbus segment from being pulled down in the event of a short circuit on any one of the individual field devices or spur cable runs.

Note During a short circuit, the shorted spur draws more current than a normal Fieldbus device - this must be taken into account in segment design.

Diagnostic aids

Each Megablock comes with a green LED to indicate whether DC Power is present, and a red LED next to each numbered spur indicates when the spur is in short circuit.

* The standard connector for the Megablock is a pluggable screw terminal (elevator type). Pluggable spring-clamp connectors rely on constant spring pressure to maintain contact with the wire. To order Megablocks with pluggable spring-clamp connectors, add a –PC suffix to the part number (i.e. F304-PC).

† Up to two bars may be required for each Megablock.

4 MecHaNIcal

4.1 Mounting orientationMegablocks mount vertically or horizontally on 35mm DIN rail within a field junction box The use of DIN rail end stops are recommended to prevent sliding (especially for vertical installations).

Eight, and twelve port Megablocks have areas on their body for labelling so that segments can be easily identified according to plant standards.

4.2 enclosure requirements

4.2.1 General requirements

Megablocks may be mounted in hazardous (classified) areas – see section 8. The following conditions must also be satisfied to ensure safe and reliable operation.

a) Prevent any form of pollution that could compromise the operation of the unit. For example, choose an unpolluted location or a suitable enclosure to protect the assembly.

b) Provide an adequate level of mechanical protection. This can be achieved by selecting a protected location, a suitable enclosure, or a combination of both.


c) Ensure that all cable entries and connections are secure by making provision for the careful routing and securing of all cables.

d) Provide adequate security against unauthorized interference.e) Conform to the permitted ambient temperature range of –40°C to +70°C.

4.2.2 outdoor mounting

In addition to the General Requirements above, if the Megablock is mounted in an outdoor location, use a suitable enclosure with a minimum of IP54 ingress protection. A higher level of ingress protection rating will be necessary if the working atmosphere is, or can be, corrosive, or if the enclosure is subject to wet or dusty environments.

4.3 DIN-rail mountingThe Megablocks are designed for mounting on 35mm x 7.5mm T-section “top hat” DIN rail to EN50022 and use built-in DIN rail clips to attach to the rail.

4.3.1 Mounting procedure

Megablocks are attached to the DIN rail using a “push-and-tilt” method - as illustrated on the body label and in Figure 4.1 below.

Tilt the Megablock towards the trunk-connector side of the Megablock and then engage the DIN-rail clips under the ledge of the DIN rail. Push the Megablock against the edge of the rail then rotate the Megablock until it sits flat onto the DIN rail, then release the pressure to allow the clips on the other side to engage.

Push 2

Figure 4.1: DIN rail Installation and removal

4.4 removal from DIN-railRefering to Figure 4.1, push the Megablock against the edge of the DIN rail, tilt the other side of the Megablock up and away from the DIN rail, then release the side pressure to disengage the DIN rail clips from the DIN rail ledge.

5 electrIcal coNNectIoNsThe Trunk and Spur connectors are pluggable (with securing screws) and available in the standard screw-terminal version or a spring-clamp version. Megablocks with spring clamp connectors have a –PC suffix on the Megablock part number (-PC). See Figures 5.1 and 5.2. The terminals can accept the following conductor sizes:

type conductor size

Screw terminals 0.14 to 2.5mm2

Spring clamp terminals (-PC) 0.20 to 2.5mm2

NoteA torque screwdriver set between 0.5 - 0.6Nm is recommended for tightening all

terminal screws.


Figure 5.3F97 terminator

Figure 5.1: screw terminal Figure 5.2: spring clamp

NoteWhen wiring to spring-clamp terminals, use a screwdriver with a 3-4 mm blade to depress the spring-clamp button before inserting the termination cable. See Figure 5.2.

5.1 Dc Power requirementsMegablocks draw DC power from the fieldbus trunk segment they are connected to. The minimum DC input voltage, and current required, vary with the Megablock type. Refer to the F300 datasheet for exact current requirements. The maximum input voltage is 32V DC, but a lower voltage may be required in order to achieve safety in some hazardous area applications - refer to the Control Drawings in Sections 9 & 10 of this manual.

5.2 terminatorA terminator (Model No. F97) is provided with each F300 Megablock. The terminator should be installed on the trunk of the last Megablock in order to correctly terminate the bus. The terminator is placed in the second set of terminals on the trunk connector.

For spring clamp terminals, push the terminator firmly into place. take care to orientate the terminator so that the “T–F97” molded logo is facing inwards towards the body of the Megablock, otherwise difficulty will be experienced in accessing the spring-clamp buttons to remove it. For screw terminals, loosen the screws, insert the terminator so that the molded logo is visible and then tighten the screws. The F97 terminator has no specific polarity but inserting it with the ‘T’ visible clearly identifies the component, and its purpose.

When not in use, the F97 should be stored in the convenient storage slot provided in the F300 body close to the trunk connection (Figure 1.1 shows it mounted this way on the F304 model).

5.3 trunk connectionsEach trunk connector provides two sets of interlinked (+), (–) and cable screen (S) connections.

The second connection enables the user to onward connect the trunk to a further Megablock and avoids breaking the connection if an “upstream” Megablock needs to be removed.

The second connection can also be used, as mentioned above, to install the F97 terminator if it is the last Megablock on the segment. See Section 5.5 for information on cable screen grounding.

WarNING !It is not permitted to connect or disconnect the trunk wiring in a hazardous area without a gas clearance certificate or unless the circuit to which it is connected has been de-energised.


5.3.1 ex na [ic] applications

When the equipment is installed in an Ex nA [ic] application, a trunk-spur partition* must be installed to segregate the trunk and spur wiring - see Figures 5.4 and 5.5.

* available in packs of five as Part No. F300-A01-5

Figure 5.4: trunk-spur partition installation

Figure 5.5: trunk-spur partition in position

Position the partition as shown in Figure 5.4 and locate the fingers into the channels on the sides of the device body. Press the partition onto the body until the fingers click into place at the bottom of the case - see Figure 5.5. The channels have different sizes so the partition cannot be installed backwards.

5.4 spur port connectionsEach spur port connector provides (+), (–) and cable screen (S) connections. See section 5.5 for information on cable screen grounding.

cable screen connections

The ‘S’ screen terminals for the trunk and the spurs are interconnected/commoned within the F3xx device and should be grounded at only one point for the whole segment (i.e. a single-point ground). The MTL recommended position for that connection is in the control room close to the power supply at the DCS, or else in accordance with local system practice.

5.5 surge protectionEach fieldbus terminal, trunk or spur, on a Megablock can be fitted with an FS32 surge protector to prevent damage to the internal components. The FS32 uses the same pluggable connector as the field connector; so the field connector is removed, the FS32 inserted and the original field connector is fitted to the FS32. See Figure 5.6 & 5.7.

Trunk - F300-BAR Spur - F312-BAR M4 ground screw locations

Figure 5.6: Typical grounding bars Figure 5.7: With some FS32 modules


Mounting brackets, known as “grounding bars”, can be fitted into ready moulded positions on both sides of the Megablock. (Grounding bar types are chosen to suit the model - see page 2.) The FS32 has a central mounting screw to provide a mechanical and electrical connection to the grounding bar. The bar must then be wired to a low-impedance, protective local ground point in order to dissipate any induced surge currents.

NoteIf a trunk-spur partition is to be fitted (Section 5.3.1), install it before mounting the FS32 modules adjacent to it.

To mount FS32 surge protection modules on a Megablock:

1. Remove and retain the pluggable terminals from one side of the Megablock.

2. Locate the grounding bar lugs in the moulded positions on the side of the Megablock and press it firmly into place - see Figure 5.6.

3. Repeat 1 and 2 for the other side of the Megablock, if required.

4. Use an M4 screw and ring terminal to connect each grounding bar to a suitable low-impedance ground point - see Figure 5.7.

5. Mount an FS32 into one of the empty sockets and tighten its two plug screws, then tighten the grounding screw into the mounting bar.

6. Insert one of the pluggable terminals into the FS32 and tighten its securing screws.

7. Repeat 5 and 6 for all the other FS32 modules.

A separate grounding bar (F300-BAR) is used for the trunk connector, which must be similarly connected to ground - see Figures 5.6 & 5.7 Follow a similar procedure to the one above for the trunk circuit.

NoteThe FS32 surge protector is not certifed for installation in a Zone 2 hazardous area and should be used only in applications where the Megablock is installed in a safe (non-hazardous) area. Consult MTL for information on surge protection in Zone 2 hazardous areas.

6 testING

6.1 Power leDEach Megablock has a green power LED (labelled PWR). This LED lights when the segment DC voltage exceeds 10V to indicate power is present.

6.2 spur leDsA red LED is located next to each Megablock spur port. The LED lights when the SpurGuard™ current-limiting function is activated by a short-circuit on the spur.

7 roUtINe MaINteNaNceCheck the general condition of the installation periodically to make sure that no deterioration has occurred. At least every two years (and more frequently for particularly harsh environments) check that:

• cable, wire connections, terminations, and screens are in good condition• the green Power LED is lit• no red spur LEDs are lit• no signs of damage or corrosion are present

WarNING !the plastic parts can store static charge. clean only with a damp cloth to prevent static buildup.
